Grade 6 Ratios & Proportional RelationshipsSample Unit Plan

This instructional unit guide was designed by a team of Delaware educators in order to provide a sample unit guide for teachers to use. This unit guide references some textbook resources used by schools represented on the team. This guide should serve as a complement to district curriculum resources.

Unit Overview

Ratios, Proportions, & Proportional Reasoning is a critical unit in the middle school years because understanding ratios and proportional reasoning is necessary to be able to work with fractions, decimals, percents, rates, unit rates, and applications of proportions. This unit builds on students’ understanding of multiplicative comparison and serves as an important foundation for grade 7 work with proportional reasoning and algebra.

Students will develop an understanding that a ratio is a multiplicative comparison of two or more quantities. When two quantities are related proportionally, the ratio of one quantity to the other is invariant as the numerical values of both quantities change by the same factor.

Proportional reasoning is useful in many real-life situations including making price comparisons, determining the best buy, finding gas mileage, scaling recipes up or down, distance on maps, calculating tips, taxes, discounts, unit conversions, etc. Students who have strong proportional reasoning are smarter consumers.

Working with ratios and proportions provides opportunities for students to reason with and use (e.g. for argumentation) a range of models and representations including ratio tables, tape models, double number lines, the coordinate plane, etc.

The Design Process

The writing team followed the principles of Understanding by Design (Wiggins & McTighe, 2005) to guide the unit development. As the team unpacked the content standards for the unit, they considered the following:

Stage 1: Desired Results What long-term transfer goals are targeted? What meanings should students make? What essential questions will students explore? What knowledge and skills will students acquire?

Stage 2: Assessment Evidence What evidence must be collected and assessed, given the desired results defined in

stage one? What is evidence of understanding (as opposed to recall)?

Stage 3: The Learning Plan● What activities, experiences, and lessons will lead to achievement of the desired results

and success at the assessments?● How will the learning plan help students Acquisition, Meaning Making, and Transfer?● How will the unit be sequenced and differentiated to optimize achievement for all

learners?

The writing team incorporated components of the Learning-Focused (LFS) model, including the learning map, and a modified version of the Know-Understand-Do template.

The team also reviewed and evaluated the textbook resources they use in the classroom based on an alignment to the content standard for a given set of lessons. The intention is for a teacher to see what supplements may be needed to support instruction of those content standards. A list of open educational resources (OERs) are also listed with each lesson guide.

Enduring Understandings & Essential Questions

Enduring Understanding (Teacher) Essential Question(s) (Student)

Understanding 1Understand the difference between part to part and part to whole and how those relationships are represented as ratios.

Understanding 2A ratio relationship is a multiplicative comparison of two quantities in which both quantities change by the same factor.

Understanding 3A rate is a set of infinitely many equivalent ratios.

Understanding 4Reasoning with ratios involves attending to and coordinating two quantities.

Understanding 5Forming a ratio as a measure of a real-world attribute involves isolating that attribute from other attributes and understanding the effect of changing each quantity on the attribute of interest

EQ1. How can rates, ratios, and proportional reasoning help us better understand the use of ratios and rates in the world around us?

EQ2. What is a ratio and how do we make sense of whether two or more ratios are proportional?

Understanding 6A proportion is a relationship of equality between two ratios that can be represented in a variety of ways. In a proportion, the ratio of two quantities remains constant as the corresponding values of the quantities change. For instance, in a ratio table, both quantities in a ratio must be multiplied or divided by the same factor to maintain the proportional relationship.

EQ3. How can I use models (tape diagrams, double number lines, ratio tables, coordinate plane, etc.) to display an understanding of ratios and proportional relationships?

Reach Back/Reach Ahead Standards

How does this unit relate to the progression of learning? What prior learning do the standards in this unit build upon? How does this unit connect to essential understandings of later content in this course and in future courses? The table below outlines key standards from previous and future courses that connect with this instructional unit of study.

Reach Back Standards Reach Ahead Standards4.OA.2 Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.

4.MD.A.1 Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

5.NF.B.3 Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

5.NF.B.4 Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

5.NF.B.5 Interpret multiplication as scaling (resizing).

5.NF.B.6 Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

5.NF.B.7 Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.

6.EE.C.9 Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between distance and time.

6.EE.B.7 Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.

7.RP.A.1 Compute unit rates associated with ratios of fractions, including ratios of lengths, areas, and other quantities measured in like or different units.

7.RP.A.2a Recognize and represent proportional relationships between quantities.

7.RP.A.2b Recognize and represent proportional relationships between quantities.

7.RP.A.3 Use proportional relationships to

5.OA.A.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them.

5.OA.B.3 Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane.

5.G.A.1 Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond.

5.G.A.2 Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

solve multistep ratio and percent problems.

7.EE.B.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

HS.G-MG.A.2 Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile, BTUs per cubic foot).

HS.N-Q.A.1 Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.

A proportion is a relationship of equality between two ratios that can be represented in a variety of ways. In a proportion, the ratio of two quantities remains constant as the corresponding values of the quantities change. For instance, in a ratio table, both quantities in a ratio must be multiplied or divided by the same factor to maintain the proportional relationship.
